What is B06B6?

The B06B6 diagnostic trouble code (DTC) is a manufacturer-specific code primarily associated with certain 2015 to 2020 Ford and Lincoln vehicles. This code indicates an issue with the rear parking aid system, which is responsible for detecting obstacles behind your vehicle when reversing. When B06B6 is triggered, it usually means there's a fault in the parking aid sensor circuit, which can lead to incorrect distance readings or complete failure of the rear parking sensors. This can significantly affect your ability to safely reverse your vehicle, especially in tight spaces. The rear parking aid system utilizes ultrasonic sensors to detect objects, and if these sensors malfunction, you might notice that the system either does not activate or provides inaccurate warnings. Owners may also experience the rear parking sensor warning light illuminating on the dashboard. Ignoring this code can lead to safety hazards while reversing, making it essential to address it promptly. Technically, the B06B6 code usually follows a thorough vehicle scan, where the OBD2 system has detected inconsistencies in the sensor feedback or wiring harness connected to the parking aid system. It’s crucial to understand that this code doesn't just affect functionality but could also influence the vehicle's overall safety systems.

System: B - Body (Airbags, Lighting, Security, Climate Control)

Symptoms

Common symptoms when B06B6 is present:

  • The rear parking sensor warning light is illuminated on the dashboard, indicating a fault in the system.
  • You may notice that the parking aid system fails to activate when the vehicle is put in reverse, preventing any obstacle detection.
  • The system could intermittently provide false alerts or fail to give warnings when objects are detected behind the vehicle.
  • You might hear unusual beeping or chirping sounds that are inconsistent with normal operation.
  • Reduced functionality of the parking aid system could lead to minor collisions or near misses when reversing.

Possible Causes

Most common causes of B06B6 (ordered by frequency):

  1. The most common cause of the B06B6 code is a faulty rear parking sensor, with a likelihood of about 50%. This could stem from physical damage or internal failure of the sensor.
  2. Another frequent cause is damaged or corroded wiring in the sensor circuit. This can lead to intermittent connectivity issues, affecting sensor performance.
  3. A malfunctioning Body Control Module (BCM) can also trigger the B06B6 code, as it plays a critical role in interpreting sensor signals and controlling the parking aid system.
  4. Less common but serious causes include water ingress into the sensor connectors or the sensors themselves, potentially leading to complete system failure.
  5. Rarely, a programming issue in the vehicle’s computer system may also produce the B06B6 code, indicating the need for a software update or reprogramming.
